Two St Vincent registered tugs SVITZER HELENA & SVITZER CELIA in the Thames Estuary this morning bound for Chatham Docks on the Medway, any info about them or their visit? Their track shows them inbound via the English Channel

Although SeaWeb shows the pair with the Svitzer names/ownership at completion, I am not sure whether they were intended for Svitzer service in Brazil with those names.They arrived at Panama in 11/2016 and were most of the time at Cristobal (working?) - SVITZER HELENA was briefly in Bunenaventura, Colombia in January. 7/2/2017 sailed Panama, and 15-19/2 were at Philipsburg, St Maarten, presumably being prepared for Transatlantic delivery.

When they arrived at Chatham they had registry port of Kingstown painted on them, but welded on letters for Rio de Janeiro (now overpainted) were clearly visible below this confirming original Brazilian registry.
